NEW QUESTION 1
A user has launched five instances with ELB. How can the user add the sixth EC2 instance to ELB?

• A. The user can add the sixth instance on the fly.
• B. The user must stop the ELB and add the sixth instance.
• C. The user can add the instance and change the ELB config file.
• D. The ELB can only have a maximum of five instance

Answer: A

Explanation: Elastic Load Balancing automatically distributes incoming traffic across multiple EC2 instances. You create a load balancer and register instances with the load balancer in one or more Availability Zones. The load balancer serves as a single point of contact for clients. This enables you to increase the availability of your application. You can add and remove EC2 instances from your load balancer as your needs change, without disrupting the overall flow of information.

NEW QUESTION 7
An orgAMzation has 10000 employees. The orgAMzation wants to give restricted AWS access to each employee. How can the orgAMzation achieve this?

• A. Create an IAM user for each employee and make them a part of the group
• B. It is not recommended to support 10000 users with IAM

making it easier to manage your users by maintaining their identities in a single place. In this case, the federated user is the only solution since AWS does not allow creating more than 5000 IAM users. Reference: http://docs.aws.amazon.com/IAM/latest/UserGuide/LimitationsOnEntities.html

NEW QUESTION 13
An orgAMzation has created 10 IAM users. The orgAMzation wants those users to work independently and access AWS. Which of the below mentioned options is not a possible solution?

• A. Create the access key and secret access key for each user and provide access to AWS using the console
• B. Create the X.509 certificate for each user and provide them access to AWS CLI
• C. Enable MFA for each IAM user and assign them the virtual MFA device to access the console
• D. Provide each user with the IAM login and password for the AWS console

Answer: A

Explanation: If an orgAMzation has created the IAM users, the users can access AWS services either with an IAM specific login/password or console. The orgAMzation can generate the IAM X.509 certificates to access AWS with CLI. The orgAMzation can also enable MFA for each IAM user, which allows an added security for each IAM user. If the orgAMzation has created the access key and secret key than the user cannot access the console using those keys. Access key and secret access key are useful for CLI or
Webservices.

NEW QUESTION 17
You are building an online store on AWS that uses SQS to process your customer orders. Your backend system needs those messages in the same sequence the customer orders have been put in. How can you achieve that?

• A. You can do this with SQS but you also need to use SWF
• B. Messages will arrive in the same order by default
• C. You can use sequencing information on each message
• D. It is not possible to do this with SQS

Answer: C

Explanation: Amazon SQS is engineered to always be available and deliver messages. One of the resulting tradeoffs is that SQS does not guarantee first in, first out delivery of messages. For many distributed applications, each message can stand on its own, and as long as all messages are delivered, the order is not important. If your system requires that order be preserved, you can place sequencing information in each message,
so that you can reorder the messages when the queue returns them. Reference:
